CBSE Class 3 Mathematics Revision Worksheet Set 04

Q1 Look at the pictograph and answer the following questions.
AFTEaR-SCHOOL CLUB MEMBERSHIP
Hobby Club: 4 person icons
Writers' Club: 3 person icons
Chess Club: 2 person icons
Art Club: 3 person icons
Drama Club: 2 person icons
Science Club: 4 person icons
Sports Club: 5 person icons
Math Club: 7 person icons
Key: Each person icon stands for 4 members.

a) Find out the number of students in the Science Club.
Answer: Science Club has 4 person icons.
Number of students = \(4 \times 4 = 16\)
In simple words: Multiply the number of icons by 4 to get the total students.

Exam Tip: Always check the key carefully before calculating values from a pictograph.

b) Find out how many students go for the Maths Club.
Answer: Math Club has 7 person icons.
Number of students = \(7 \times 4 = 28\)
In simple words: Multiply 7 icons by the key value 4.

Exam Tip: Count the icons accurately row by row.

c) Total number of students in the Hobby club and the Drama Club.
Answer: Hobby Club has 4 icons (\(4 \times 4 = 16\) students) and Drama Club has 2 icons (\(2 \times 4 = 8\) students).
Total students = \(16 + 8 = 24\)
In simple words: Find students in both clubs and add them together.

Exam Tip: You can also add the total number of icons first (\(4 + 2 = 6\)) and then multiply by 4 (\(6 \times 4 = 24\)).

d) The club having the maximum members.
Answer: Math Club (7 icons, which equals 28 members)
In simple words: Look for the row with the highest number of icons.

Exam Tip: The club with the longest line of icons has the maximum members.

e) The club having the least members.
Answer: Chess Club and Drama Club (both have 2 icons, which equals 8 members)
In simple words: Look for the rows with the fewest icons.

Q2 Look at the pictograph and answer the following questions.
Favorite Pizza Toppings
cheese: 5 pizza icons
mushroom: 4 pizza icons
sausage: 4 pizza icons
pepperoni: 5 pizza icons
Key: Each pizza icon = 5 pizzas

a) Which is the most favourite pizza topping?
Answer: Cheese and Pepperoni (both have 5 pizza icons, representing 25 pizzas each)
In simple words: Both cheese and pepperoni have the highest number of pizza icons.

Exam Tip: Check for ties when identifying maximum values in data.

b) How many pizzas are with mushroom topping?
Answer: Mushroom topping has 4 pizza icons.
Total pizzas = \(4 \times 5 = 20\)
In simple words: Multiply the 4 mushroom icons by the key value 5.

Exam Tip: Always multiply by the number given in the key.

c) How many pizzas have cheese toppings?
Answer: Cheese topping has 5 pizza icons.
Total pizzas = \(5 \times 5 = 25\)
In simple words: Multiply 5 icons by 5.

Exam Tip: Verify the count of icons for the cheese row carefully.

Q3 Choose the operation for solving the following.

a) There are 200 oranges in a basket. How many oranges are there in 4 such baskets?
Answer: Multiplication
Calculation: \(200 \times 4 = 800\) oranges
In simple words: When you know the amount in one group and need the total for multiple equal groups, use multiplication.

Exam Tip: Key words like "each" or "such baskets" usually indicate multiplication.

b) 600 crayons are shared among 6 students equally. How many crayons did each student get?
Answer: Division
Calculation: \(600 \div 6 = 100\) crayons
In simple words: When items are shared equally among a group, use division.

Exam Tip: Words like "shared equally" mean you should divide.

c) There are 22 bags of onions. Each bag contains 376 onions. How many onions are there in all?
Answer: Multiplication
Calculation: \(376 \times 22 = 8272\) onions
In simple words: Multiply the number of bags by the quantity in each bag.

Exam Tip: "In all" combined with "each bag" points directly to multiplication.

d) In an orchard there are 1821 mango trees, 200 litchi trees and 250 guava trees. How many trees are there in all?
Answer: Addition
Calculation: \(1821 + 200 + 250 = 2271\) trees
In simple words: Combine all the different types of trees together using addition.

Exam Tip: Finding the combined total of different items requires addition.

e) If 4500 passengers were travelling by a train to Chandigarh. 1500 passengers got down on the way. How many passengers reached Chandigarh station?
Answer: Subtraction
Calculation: \(4500 - 1500 = 3000\) passengers
In simple words: Subtract the people who left from the total initial passengers.

Exam Tip: Phrases like "got down" or "left" indicate subtraction.

Q4 Find.
a) 100 less than 4806
Answer: \(4806 - 100 = 4706\)
In simple words: Subtract 100 from 4806.

Exam Tip: "Less than" means subtraction.

b) 10 multiplied by 800
Answer: \(10 \times 800 = 8000\)
In simple words: Add one zero to 800 when multiplying by 10.

Exam Tip: Multiply the non-zero digits and append the total number of zeros.

c) 1000 divided by 100
Answer: \(1000 \div 100 = 10\)
In simple words: Cancel out two zeros from both numbers.

Exam Tip: Division by powers of 10 involves moving the decimal point or crossing out matching zeros.

d) Smallest 4 digit number + _________ = 9000
Answer: 8000
Calculation: Smallest 4-digit number = 1000
\(9000 - 1000 = 8000\)
In simple words: Subtract 1000 from 9000 to find the missing number.

Exam Tip: Remember that the smallest 4-digit number is 1000.

Q5 Solve and find the quotient and the remainder.
a) \(683 \div 3\)
Answer: Quotient = 227, Remainder = 2
Step-by-step division:
\(3 \times 2 = 6\) (bring down 8)
\(3 \times 2 = 6\), remainder 2 (bring down 3)
\(3 \times 7 = 21\), remainder 2
In simple words: Divide 683 by 3 to get 227 with 2 left over.

Exam Tip: Verify your answer using: \((\text{Quotient} \times \text{Divisor}) + \text{Remainder} = \text{Dividend}\) (\(227 \times 3 + 2 = 683\)).

b) \(749 \div 7\)
Answer: Quotient = 107, Remainder = 0
Step-by-step division:
\(7 \times 1 = 7\) (bring down 4, which is less than 7, so write 0 in quotient)
Bring down 9 to make 49
\(7 \times 7 = 49\), remainder 0
In simple words: 7 goes into 749 exactly 107 times.

Exam Tip: Be careful with intermediate zeros in the quotient when a digit is smaller than the divisor.

Q6 Arrange in columns and solve.
a) \(1546 + 897\)
Answer: 2443
Arrangement in columns:
    1 5 4 6
+     8 9 7
------------
    2 4 4 3
In simple words: Add column by column from right to left with carrying over.

Exam Tip: Always align numbers by their place values (ones under ones, tens under tens).

b) \(8009 \times 8\)
Answer: 64072
Arrangement in columns:
    8 0 0 9
\(\times\)        8
------------
  6 4 0 7 2
In simple words: Multiply 8 by each digit of 8009 from right to left.

Exam Tip: Pay special attention when multiplying across zeros and adding carried numbers.

c) \(5986 - 207\)
Answer: 5779
Arrangement in columns:
    5 9 8 6
-\       2 0 7
------------
    5 7 7 9
In simple words: Subtract column by column from right to left, borrowing when necessary.
